Abstract
Provided herein is a vibration reducing sheet comprising a damping patch, a stiffening patch, and a substrate. The substrate is connected to the damping patch and the stiffening patch, and in some embodiments, the damping patch and the stiffening patch do not contact one another. The sheet can be connected to a base structure that is prone to vibrations. Because the damping patch and the stiffening patch can thus be applied to different locations of the base structure, the two patch types can independently be positioned to provide enhanced vibration reduction and mitigation.

A vibration reduction sheet comprising:
- a damping patch having a Young's modulus;
- a stiffening patch having a Young's modulus, wherein the ratio of the stiffening patch Young's modulus to the damping patch Young's modulus is greater than or equal to 100;
- and
- a substrate having a substrate face in contact with the damping patch and the stiffening patch, wherein the damping patch and the stiffening patch are not in contact with one another.
